So if m3 is 35 and m4 is 98 & m1 is 47 = 180 then m3 + m4 = 133. m1 + m2= 180 since 1 and 2 are supplementary they equal 180 so m2 = 133 and m2 is equal to m3 and m4
Hopes this helps and if you need any clarification just let me know. (:
a) New price = 1.13 * Original price
b) New price = 37,742
Given:
47% of 89
Exact solution is : 0.47 * 89 = 41.83
Estimates: you round the number to the nearest tens.
47% can be 50% ; 89 can be 90
0.50 * 90 = 45
50% is the same as 1/2
1/2 * 90 = 45
90/2 is also applicable to estimate for the above figure. 90/2 = 45
